A local guy bought an old 8mm mauser and wants to reload for it and was told it has a bore size of one size and then a bore size of another size.
So to be sure it will need to be slugged.
What's the easiest way to slug a barrel?
I watched a YouTube video and they took a over sized blackpowder round ball and forced it through the barrel with pieces of a wood dowel them measured it.
They measurd the grooves and the outside diameter and said to go I thousands of an inch over the outside diameter.
His rifle is suppose to be a 8mmJ.
.317 diameter.
So if it is the smaller .317 bore would the expander need to be different from the standard 8mm expander ball?
